SPECIFICATION forming part of Letters Patent No. 440,860, dated November 18, 1890.

Application filed July 8,1890- Serlal No. 357,634. (No model.)

To aZZ whom it may concern.-

Be it known that I, SAMUEL BROOKE, a citi zen of the United States, residing at Mackville, in the county of Stafford and State of Kansas, have invented a new and useful Cultivator, of which the following is a specification.

This invention relates to cultivators; and it has for its object to construct a device of this class which shall be simple, durable, and efficient in operation.

With these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will. be hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a cultivator embodying my improvements. Fig. 2 is a longitudinal sectional view of the same. Fig. Sis a rear view. Fig. 4 is a side elevation showing the cultivator provided with stationary instead of rolling colters.

Like numerals of reference indicate like parts in all the figures.

1 1 designate runners, which may be of any desired dimensions. Said runners are provided at their upper edges, near their front and rear ends, with lateral outwardly extending brackets 2 2.

3 3 designate arches provided with outwardly-extending arms a, which are connected adjustably with the brackets 2 by means of bolts 5, passing through perforations in the said arms and brackets, and thus connecting the runners together. In this manner it will be seen that the said runners may be spaced any desired distance apart.

To the outer sides of the runners, near the rear ends of the latter, are secured plows 6 6, which are curved in an upward and outward direction. Said plows are provided at their inner edges with flanges 7 to receive the bolts, by means of which they are secured detachably to the runners. These plows may be reversed or changed from one side of the cultivator to the other so as to throw the dirt from or toward the plants, as may be desired.

To the inner sides of the runners, near their rear ends, are secured the subsoilers 8. These, like the plows 6, are provided with flanges having perforations to receive the bolts, by means of which they are secured to the runners. Said subsoilers may be raised or lowered or adjusted to any desired position which may be found most advantageous for the work that is to be accomplished.

To the inner sides of the runners slightly in advance of the subsoilers may be secured the rolling colters or cutters. These devices are not always necessary, but will be found desirable when the soil contains roots or trash requiring to be out. In lieu of the rollin g colters, stationary cutters may be used, as shown in Fig. i of the drawings, said stationary cutters being preferably bolted to the outer sides of the runners.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. The draft may be attached to the brackets at the front ends of the runners. When young corn is to be cultivated, the plows 6 should be adj usted to throw the dirt away from the plants. When the plants grow older, the plows are reversed to throw the dirt toward the plants. The subsoilers are not necessarily used. Vhen used, however, they will cut deeply into the soil, the surface of ,the soil being lightly stirred or agitated by the plows 6. In land containing fruits or trash the colters will be found useful to out the soil in advance of the plows and subsoilers.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination of the runners, the arches connecting the same, the outwardly and upwardly curved plow-blades secured detachably and interchangeably at the rear ends of the runners, and the subsoilers secured to the inner sides of the latter, substantially as set forth.

2. The combination of the runners, the arches connecting the same, the plows secured to the outer sides of said runners, and the subsoilers secured to the inner sides of the same, substantially as set forth.

3. The combination of the runners, the my own Ihave hereto affixed my signature in arches connecting the same, the plows secured presence of two Witnesses. to the outer sides of the runners, the subsoilers secured to the inner sides of the same, SAMUEL BROOKE 5 and the colters or cutters, substantially as and Witnesses:

for the purpose set forth. t J. E. FINN,

In testimony that I claim the foregoing as A. H. CARPENTER.
